At CES 2. 01. 6 we saw that DRIVE PX2 had a new Tegra So. C in it, but to some extent NVIDIA was still being fairly cagey about what was actually in this So.

Fortunately, at Hot Chips 2. Tegra Parker and DRIVE PX2. Explore research at Microsoft, a site featuring the impact of research along with publications, products, downloads, and research careers. Starting with Parker, this is an So. C that has been a long time coming for NVIDIA. Windows 7 Serial Port Terminal'>Windows 7 Serial Port Terminal. The codename and its basic architectural composition were announced all the way back at GTC in 2. Logan Tegra K1 So.

However Erista Tegra X1 was later added mid generation and wound up being NVIDIAs 2. So. C so until now the fate of Parker has not been clear. As it turns out, Parker is largely in line with NVIDIAs original 2. Maxwell GPU we get something based off of the newer Pascal architecture. But first, lets talk about the CPU. The CPU complex has been disclosed as a dual core Denver 2 combined with a quad core Cortex A5. Maxwell Sv Software Companies' title='Maxwell Sv Software Companies' />So. C running on TSMC 1. Fin. FET process. This marks the second So. C to use NVIDIAs custom developed ARM CPU core, the first being the Denver version of the Tegra K1. Relative to K1, Parker I suspect NVIDIA doesnt want to end up with TP1 here represents both an upgrade to the Denver CPU core itself, and how NVIDIA structures their overall CPU complex, with the addition of a quartet of ARM Cortex A5. Denver 2 cores. The big question for most readers, I suspect, is about the Denver 2 CPU cores. NVIDIA hasnt said a whole lot about them bearing in mind that Hot Chips is not an exhaustive deep dive style architecture event so unfortunately theres not a ton of information to work with. ATV.jpg' alt='Maxwell Sv Software Companies' title='Maxwell Sv Software Companies' />What NVIDIA has said is that theyve worked to improve the overall power efficiency of the cores though Im not sure if this factors in 1. Fin. FET or not, including by implementing some new low power states. Meanwhile on the performance side of matters, NVIDIA has confirmed that this is still a 7 wide design, and that Denver 2 uses an improved dynamic code optimization algorithm. What little that was said about Denver 2 in particular was focused on energy efficiency, so it may very well be that the execution architecture is not substantially different from Denver 1s. With that in mind, the bigger news from a performance standpoint is that with Parker, the Denver CPU cores are not alone. For Parker the CPU has evolved into a full CPU complex, pairing up the two Denver cores with a quad core Cortex A5. NVIDIA cheekily refers to this as Big Super, a subversion of ARMs big. LITTLE design, as this combines big A5. Denver cores. There are no formal low power cores here, so when it comes to low power operation it looks like NVIDIA is relying on Denver. That NVIDIA would pair up Denver with ARMs cores is an interesting move, in part because Denver was originally meant to solve the middling single threaded performance of ARMs earlier A series cores. Secondary to this was avoiding big. LITTLE style computing by making a core that could scale the full range. For Parker this is still the case, but NVIDIA seems to have come to the conclusion that both responsiveness and the total performance of the CPU complex needed addressed. The end result is the quad core A5. Denver cores. NVIDIA didnt just stop at adding A5. Heterogeneous Multi Processing HMP design. A fully coherent HMP design at that, utilizing a proprietary coherency fabric specifically to allow the two rather different CPU cores to maintain that coherency. The significance of this besides the unusual CPU pairing is that it should allow NVIDIA to efficiently migrate threads between the Denver and A5. This also allows NVIDIA to use all 6 CPU cores at once to maximize performance. And since Parker is primarily meant for automotive applications featuring more power and better cooling unlike mobile environments its entirely reasonable to expect that the design can sustain operation across all 6 of those CPU cores for extended periods of time. Overall this setup is very close to big. LITTLE, except with the Denver cores seemingly encompassing parts of both big and little depending on the task. With all of that said however, it should be noted that NVIDIA has not had great luck with multiple CPU clusters Tegra X1 featured cluster migration, but it never seemed to use its A5. CPU cores at all. So without having had a chance to see Parkers HMP in action, I have some skepticism on how well HMP is working in Parker. Overall, NVIDIA is claiming about 4. CPU performance than A9x or Kirin 9. Maxwell Sv Software Companies' title='Maxwell Sv Software Companies' />CPUs in the system then its going to be noticeably faster than two Twister CPUs at 2. GHz. But theres no comparison to Denver 1 TK1 here, or any discussion of single thread performance. Though on the latter, admittedly Im not sure quite how relevant that is for NVIDIA now that Parker is primarily an automotive So. Pokerstars Free Money Hack. C rather than a general purpose So. C. Outside of the CPU, NVIDIA has added some new features to Parker such as doubling memory bandwidth. For the longest time NVIDIA stuck with a 6. So. C lineup, which despite what you may think from the specs worked well enough for NVIDIA, presumably due to their experience in GPU designs, and as weve since learned, compression tiling. Parker in turn finally moves to a 1. GBsec which works out to roughly LPDDR4 3. More interesting however is the addition of ECC support to the memory subsystem. This seems to be in place specfically to address the automotive market by improving the reliability of the memory and So. C. A cell phone and its user can deal with the rare bitflip, however things like self driving vehicles cant afford the same luxury. Though I should note its not clear whether ECC support is just some kind of soft ECC for the memory or if its hardwired ECC NVIDIA calls it in line DRAM ECC. But its clear that whatever it is, it extends beyond the DRAM, as NVIDIA notes that theres ECC or parity protection for key on die memories, which is something wed expect to see on a more hardened design like NVIDIA is promoting. Finally, NVIDIA has also significantly improved their IO functionality, which again is being promoted particularly with the context of automotive applications. Theres more support for extra cameras to improve ADAS and self driving systems, as well as 4. Kp. 60 video encode, CAN bus support, hardware virtualization, and additional safety features that help to make this So. C truly automotive focused. The hardware virtualization of Parker is particularly interesting. Its both a safety feature isolating various systems from each other while also allowing for some cost reduction on the part of the OEM as there is less need to use separate hardware to avoid a single point of failure for critical systems. Theres a lot of extra logic going on to make this all work properly, and things like running the dual Parker So. Cs in a soft lockstep mode is also possible. In the case of DRIVE PX2 an Aurix TC2. Parker So. Cs, with a PCI E switch to connect the So. Cs to the GPUs and to each other. Worms 4 Mayhem Rar there. Meanwhile, its interesting to note that the GPU of Parker was not a big part of NVIDIAs presentation. Part of this is because Parkers GPU architecture, Pascal, has already launched in desktops and is essentially a known quantity now. At the same time, Parkers big use at least within NVIDIA is for the DRIVE PX2 system, which is going to be combining Parker with a pair of d.
